A few days after each AP Calculus BC exam, the College Board releases the free response questions from the exam. They don’t release their very succinct answer keys for a few more weeks… so… I had my students make their own answer keys as well as screen recordings of their solutions!
Official 2021 answer keys will eventually go online right here, along with the ones from past years that have already been posted.
You can view the 2021 AP Calculus BC Free Response Questions right here.
All of the 2021 answer keys that my students created can be viewed right here.
All of their 2021 video solutions can be viewed right here.
You can check out this project from past years here (2019), here (2018), here (2017), and here (2016).
Many more Williston student screencasts can be found online right here.
